Official American League (Barnard) baseball signed in black fountain pen by twenty-two members of the 1929 World Champion Philadelphia Athletics, including Cochrane (sweet spot), Foxx, Simmons, Collins, Grove, Earnshaw (sweet spot), Rommel, Dykes, Perkins, Walberg, Bishop, Hale, Miller, Boley, Haas, and Ehmke. The signatures range in grade from 1/10 to 5/10, averaging 3/10. Although every legible signature on the ball belongs to a player who was on the Philadelphia Athletics in both 1928 and 1929, the ball specifically dates to the 1929-31 manufacturing period, thereby confirming its 1929 year of signing. The ball displays light soiling with several small scuffs and abrasions. Full LOA from PSA.
